Question about Harman Kardon AVR 225 Receiver

Open Question

Humming and on Screen Menu shakes fast back and forth

Harman Kardon AVR 225 5.1 When powered on the amp works fine but after 2 min. or so there is a low hum in the speakers and then the on screen menu begins to shake rapidly and disappears and works fine after a minute or two.I had the amp serviced and the tech corrected bad soldering spots. However I still have this problem. Is it a Ground Loop, bad or week output fuses? The tech said there were no bad caps or power supply problems. Any ideas or responses would be greatly appreciated. Regards, Kenneth Campbell

SOURCE: How to I reset my

Hi odysy

I got this from the manual page 43.

Resetting the Remote Memory
As you add components to your home-theater
system, occasionally you may wish to totally
reprogram the remote control without the confusion
of any commands, macros or ”Punch-
Through“ programming that you may have done.
To do this, it is possible to reset the remote to the
original factory defaults and command codes by
following these steps. Note, however, that once
the remote is reset, all commands or codes that
you have entered will be erased and will need to
be re-entered:
1. Press any of the Input Selector buttons 4
and the ”O“ button Hat the same time until
the Program/SPL Indicator 2begins to flash
2. Press the ”3“ button Hthree times.
3. The red LED under the Input Selector4
will go out and the Program/SPL Indicator
2will stop flashing and turn green.
4. The Program/SPL Indicator 2will remain
green until the remote is reset. Note that this may
take a while, depending on how many commands
are in the memory and need to be erased.
5. When the Program/SPL Indicator 2goes
out, the remote has been reset to the factory settings.

SOURCE: Harman Kardon AVR 135 6.1....AUDIO DELAY???

This model does have a delay function. Programming is on page 19 of the user manual. Go to select all products, AVR135, and get the owner's guide. If you have trouble with the link, then go to the Harmon Kardon site, and make your way to the support portal and then select all products.

SOURCE: My Harman Kardon receiver (

I used the live chat and the problem was resolved.
Usually the problem are strands of speaker wires which cause shorting and protection shuts off the receiver in order to prevent damage. There was one speaker that I repositioned recently which was causing shorting. I twisted the wires and tightened them in place and my receiver has been working w/o a glitch. I was lucky that I did not have to check all the wire strands on the receiver and all the speakers.
Problem solved and I learned valuable lesson.

SOURCE: can I conect harman Kardon avr 230 to apple tv

Yes, although it (AVR) does not support HDMI only component video.

Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.

Well it it might not. What exact model TV?

Your high-fidelity equipment should get TV-related audio from the same place the TV gets it - Cable, DVD, BD or Sat. A digital feed each of them will carry TRUE Dolby Digital audio. There is little sense in diluting TV-related audio through a TV and it's marginal audio electronics that are usually limited to analog stereo.

Humming noise

Usually Humming noises come from frequency interferance.  In this case it is being caused by your input sources.  A smiply solution is to replace the cables and or seperate the source cables away from any electircal cords or sources.

Harman kardon just went dead

You may have overloaded it. Let it rest and cool down. Check the resistance on the speaker to make sure it is in spec with your amp.

Make sure someone didn't accidentally mute it or bump the audio in source wiring.

Make sure your speaker choice (A or B or both or none for headphones only) is correct.

Was using the harmon kardon avr 225 receiver and the front panel went out. .... screen display of the channel number, volume, or menu item does not work. ...

Try hooking up a yellow video wire from the back of the AVR 225 Monitor out. Should be at the end of the 7 or 8 yellow video ports on the back of the stereo. Next plug the other end into a yellow video in on a t.v. Get your remote, (Harmon/Kardon) and make sure the t.v. is on the correct video input and hit the OSD(on screen display) button on your harmon remote. There should be a setting in there that says VFD under ADVANCED menu option that allows for turning the front of your stereo lights on and off and dimming them half way also. OFF/HALF/FULL are the 3 options I believe.

If this doesnt solve it your display may have crapped out on you.

Harman Kardon AVR 120 turns off by itself after normal work for about 1 min

Do you get an indication on the display where the point of failure might be? It would show up on the LCD speaker diagrams just before shutting off.
